of the Republic of Austria, residing and useful Improvements in Starting Devices tor Hydraulic Pumps, of which the following is a specification.

This invention relates to a new and useful improvement in starting devices for hydraulic pumps and relates in particular to a device for starting a hydraulic ram.

The principal object of this invention is to produce a device of this character which will operate upon a ram in such a manner as to start the same operating when, through i of water, the ram has ceased to operate.

further object of this invention is to provide starting device for pumps which is operated by the overflow from the source of supply and to provide an attachment which will not interfere with the delicate recoil of the pump.

A. still further object is to produce a device which is simple in construction, automatic in operation and one which may be attaelied to rams now in general use.

I propose to accomplish the above results by providing a simple means of automatically opening the interrupter valve of the ram, thereby again starting the ram.

Other objects and advantages of the invention will be apparent during the course of the following description:

in the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a diagrammatic view of a ram having my starting device attached thereto,

Figure 2 is a side elevation of a portion of my starting device, and

Figure 3 is a cross-sectional fragmentary detail view of a bucket.

T he operation of a ram is well known, and is a device which is placed in a running stream, which device serves to lift a portion of the water passing there-through and dcliver the same at some elevation above the ram. The lift is secured through the fact that the water flowing there-through is interrupted at intervals, which causes the inertia of the water trapped to be delivered at a distant point.

It is to the interrupter valve that my vention will be attached,

In the drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a ram as a whole, and the numeral 6 the interrupter valve as a whole.

The pipe 7 is adapted to receive water from a source of supply here shown as a tank 8. This tank receives its supply through a pipe 9, the pipe 9 representing a brook or any other source of supply.

The numerals 11 and 12 refer to standards positioned adjacent to the ram 5 and serving to support a bucket 13. This bucket is provided with ears 14. and 16 which serve to guide the same upon the standards 11 and 12.

At 17 I provide a brace which forms a stop to limit the downward movement of the bucket 13. This brace also serves to support a valve adjustment screw 18, which screw is adapted to be adjusted so as to contact with a valve 19 formed in a spigot 21 carried upon the bucket 13.

This bucket 13 is provided across its top with a brace 22 to which is attached a screw eye 23 through the medium of a bolt 24. To this screw eye is attached a link 26, which in turn is attached to the end of a lever 27, which lever is fulcrumed at 28 in the top of the standard 11 and is provided with a long arm 29 having a weight 31 movable thereon.

At 32 I have shown a lever adapted to contact with the arm 29 and attached at its lower end to the standard 11, through the medium of a pin This lever 32 may be lowered by moving the pin 33 to any one of the holes 34.

The numeral 36 designates an overflow pipe extending from a point near the top of the receptacle 8 to a point within the top of the bucket 13.

At 37 I have shown an arm pivoted at 38 to a bracket 39 attached to the ram 5. This arm 37 is normally adapted to rest above the stem 4-1 of the interrupter valve 6 and is adapted to have its free end engaged by a pin. 42 passing there-through and secured to the bucket 13. Between the arm 37 and the stem 41 there is a space provided when the arm is in its normal position. The position of the arm 37. as shown inFigure 2, sets forth the position of the bucket when it is down causing the stemof the valve to be depressed. The arm 37, it will be observed, will move upwardly and downwardly with the bucket and will cause an adjustable screw 43 mounted thereon to contact with the valve stem 41 only after the bucket has in its downward movement acquired a sullicient momentum to overcome the counterweight and the pressure under the valve" The above mentioned screw 4E3 on which are mounted nuts 4-4, is provided to allow different adjustments of arm 87 in order to have it disposed on a level from the pivot point 88 to the pin d2 no matter what the height of the valve stem 41 may be.

In operation water flows from the source of supply to the tank 8 through the pipe 7 through the ram 5 and causes tl :2 same to operate it being assumed that the operation has been started.

Now, assuming that the wat r supply lowers ton point where it is not suliicient to work the ram, the interrupter valve'6 will close, thereby causing the water to accumu late in the tank 8,' due to the fact that it cannot pass through'the ram 5. Y

This accumulation willresult in the water overfiowing through the'pipe 36 and dis; charging into the bucket 13, and as the bucket is empty, it will be in its dotted po sition as shown in Fi ure 1. As'soon as the same is sufficiently filled to overcome the weight 31, the bucket will move down wardly. This will cause the interrupter valve stem 1-1 to be depressed and at. the same time the valve 19 will have been lifted through the action of the valve adjustment screw 18, which will allow the water within the bucket 13 to escape, and will again allow the bucket to return to its normal position, which action carries the arm from 1ts contacting pos1t1on to its normal pos tlon.

lhis depression of the valve ,stem 41 will have started the ram to operate, which operation will continue until the supply in the tank Shas become exhausted after which the operation just described will be repeated. I

It will thus be seen that I have created a device for automatically starting a ram, which will need practically no attention.

It is tobe understood that the form of my invention herewith shown and described, is to be taken as'a preferred example of the same; and that-various changes in the shape size and arrangement or" parts may be re sorted to without departing from thespirit of the invention or joined claim.

Havingthusdescribed my invention, 1 claim v I V In an automatic'starting device for hydraulic rams, the combination of'an inter-- rupter valve, a lever-adapted to contact and depress said valve, a bucket adapted to actuate said lever, a reservoir, overflow means for conductin fluid from said reservoirto said bucket, an adjustable element for controlling the downward movement of said bucket when full of fluid and to raise said bucket when empty, andadjustable means for emptying said bucket'when said bucket has reached the limit or" its downward move ment. y
